43. Searches for Long-Lived Particles with MATHUSLA

The Large Hadron Collider (LHC) may be producing a significant number of neutral Long-Lived Particles (LLPs) with masses above a GeV, yet these elusive particles could be escaping detection by the main experiments. To bridge this gap, we propose the MATHUSLA detector (MAssive Timing Hodoscope for Ultra-Stable neutraL pArticles), a dedicated surface-based experiment positioned above CMS,...

28. Update on the CODEX-b Experiment

The COmpact DEtector for EXotics at LHCb (CODEX-b) is a particle physics detector dedicated to displaced decays of exotic long-lived particles (LLPs), compelling signatures of dark sectors Beyond the Standard Model, which arise in theories containing a hierarchy of scales and small parameters. The CODEX-b detector is a cube with 10m per side with two internal sections, planned to be installed...

39. Exploring the Projected Sensitivity of the ANUBIS detector to exotic LLP models

Michael Revering (University of Cambridge (GB))

Despite the success of the Standard Model (SM) there remains behaviour it cannot describe, in particular the presence of non-interacting Dark Matter, which composes a significant fraction of the Universe’s matter. Many models that describe dark matter can generically introduce exotic Long-Lived Particles (LLPs). The proposed ANUBIS experiment is designed to search for these LLPs within the...

11. SHIFT: Shifted Interaction on a Fixed Target

Jeremi Niedziela (Deutsches Elektronen-Synchrotron (DE))

SHIFT is a proposed extension of the LHC research program by installing a gaseous fixed target ≈150 meters upstream of CMS, delivering collisions at the center of mass energy of ≈115 GeV. The particles produced in such collisions, or their decay products, travel through the rock and other material on their path, potentially reaching the CMS detector where they can be registered and studied....
